A kind of fiber/ceramic/metal composite materials armour and preparation method thereof
Technical field:
The present invention relates to the preparation method of composite bullet-resistant plate, particularly relate to a kind of fiber/ceramic/metal bullet proof composite plating and preparation method thereof.
Background technology:
Existing armour mainly contains three kinds, and the first is steel alloy armour, and this armour toughness is better, but hardness is lower.The second is ceramic bulletproof plate, and the little hardness of this armour density is high, but impact resistance is poor, easily broken.The third is the stacked bullet proof composite plating of metal/ceramic, and the intensity of metallic plate and ceramic wafer combination is low, and under the strike effect of High-velocity Projectiles, the effect that absorbs bullet energy is undesirable.
Traditional stacked bullet proof composite plating is conventionally made panel, with the good metal of toughness or fibrous composite, is made backboard with harder pottery, sticks with glue agent bonding between the two.Yet, this structural disadvantages is just simply by adhesive, to be bonded together between layer and layer, in the process of projectile impact armour, because huge vibrating effect causes the avalanche phenomenon between layer and layer, lost as bullet proof composite plating and jointly resisted the effect that bullet impacts.
Chinese patent 201201251068.8 discloses a kind of porous metals packaging ceramic composite protective plate and preparation method thereof, this protective plate comprises at least one deck ceramic core plate, also comprise the porous metals that at least one deck ceramic core plate wraps up also and its metallurgical binding is integrated, although this idea has solved the collapsing from phenomenon between causing layer by layer of huge dither effect in projectile impact process, make armour keep out as a whole bullet, but porous metals are lower as direct out surface hardness, greatly weakened the bulletproof effect of armour.
At present, ceramic/metal armour existing problems are: 1. armour collapses between layers from phenomenon in being subject to the process of projectile impact; 2. metal is directly poor as meeting diving board bulletproof effect.
Summary of the invention:
In order to solve above-mentioned problems of the prior art, the object of the present invention is to provide a kind of fiber/ceramic/metal bullet proof composite plating and preparation method thereof, this bullet proof composite plating has good shock resistance, solved in bullet impact process and collapsed from phenomenon between layers, and metal is as the poor phenomenon of direct out surface bulletproof effect.
For achieving the above object, the technical solution adopted in the present invention is:
Fiber/ceramic/metal composite materials armour, at least comprises the composite plate structure of layer of metal sidewise restraint resin.
As the fibrage of direct out surface and the composite plate of ceramic layer and metal sidewise restraint resin, form sandwich structure, by adhesive by fibrage with ceramic layer glueds joint and use ceramic surface metallization method that ceramic layer and metal sidewise restraint resin composite plates are welded together.
The metal of metal sidewise restraint high-performance fiber composite plate of the present invention adopts titanium alloy, and resin adopts ultra-high molecular weight polyethylene.
Fibrage of the present invention adopts carbon fiber.
Ceramic layer of the present invention is the sheet material that aluminium oxide, aluminium nitride, silicon nitride, carborundum or boron carbide are made.
A concrete preparation method for fiber/ceramic/metal bullet proof composite plating, step is as follows:
Step 1: prepare titanium alloy frame 1 by Laser Welding;
Step 2: prepare ultra-high molecular weight polyethylene board 2 according to the size of titanium alloy die cavity;
Step 3: use adhesive ultra-high molecular weight polyethylene board to be fixed in the die cavity of titanium alloy frame;
Step 4: use adhesive to connect carbon fiber layer and ceramic layer;
Step 5: the most complicated be to realize being connected of pottery and metal, because ceramic and metal belongs to two kinds of diverse materials, be difficult to realize combination between atom.The most often using ceramic surface metallization method is first ceramic surface to be carried out to metalized, adopt sintering or other method in ceramic surface coating layer of metal as intermediate layer, then use solder the coat of metal together with solder bonding metal.The method of ceramic surface metallization has a lot, often adopts Mo-Mn method.Technical process is: Mo-Mn powder is made to paste and be coated in ceramic surface, in the N2 of 1000~1800 ℃ or H2 atmosphere, after sintering, surface forms glassy phase, and part metals oxide is reduced simultaneously, produces matallic surface layer, finally at plated surface last layer metal.Finally realize the direct welding of a kind of metal and metal, just become relatively easy.
The major advantage of fiber/ceramic/metal bulletproof composite version of the present invention has fiber, pottery and metal characteristic separately concurrently, and fibrage and ceramic layer have been given full play to the characteristic of they high rigidity own as direct out surface, effectively keep out bullet.Then metal sidewise restraint resin composite plates has the feature of good toughness, and effectively preventing layer collapses from phenomenon with layer, makes the as a whole bullet that effectively stops.
